similar to: "CentOS on a stick"

Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the

This is pretty epic if true. I'm installing some Fail 2008r2 now to check. Is your hypervisor running CentOS 6 or 7? -- Sent from the Delta quadrant using Borg technology!

Hi, today we ran into a strange problem: When performing a regular Windows 2008r2 update apparently among other things the following was installed: "SUSE - Storage Controller - SUSE Block Driver for Windows" Previously the disk drive was using the Red Hat virtio drivers which worked just fine but after the reboot after the update I just get a blue screen indicating that Windows cannot

Do you need the whole configuration? On the switch end, we have the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris. On Fri, Jan 23, 2015 at 8:54 PM, Dennis Jacobfeuerborn < dennisml at

Andrew and Dennis are spot on. Their conclusions about your server being connected to an access port and not a trunk port would be my conclusion as well.

Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some

Hi, I ran into a Problem when using alias interfaces with vlans on a centos 5 box. When I define such an interface and do a "service network restart" the alias interface doesn't get started. Starting it manually works fine. Also after changing DEVICE=eth0.10:0 to DEVICE=eth0:0 in the config file the interface is started after a network restart. Does anyone have an idea what the

Hi, I recently did some benchmarking on a Rackspace VM and was surprised that bonnie++ showed a read throughput of almost 500MB/sec. Does anyone have an idea how they achieve these speeds in a shared environment? While you can achieve this with a RAID easily these days once you have lots of VMs accessing that array I would expect that speed to go down quite a bit. Was I just lucky that I was

CentOS 8.0 1905 is using Linux Kernel 4.18? Not Linux Kernel 5.x?

Hi, I'm thinking about how to go about migrating our Xen VMs to KVM. Migrating the configuraton should be easy using the virsh dumpxml/define commands but what is the best way to transfer the (logical volume based) images without too much downtime for the guest system? Can rsync operate on logical volumes? If so I could potentially use "dd" to transfer an initial copy of the

Hi, I'm currently looking for a RAID controller with BBU/CacheVault and while LSI MegaRaid controllers worked well in the past apparently they are no longer supported in RHEL 8: https://access.redhat.com/discussions/3722151 Does anybody have recommendations for for hardware controllers with cache that should work in both CentOS 7 and 8 out of the box?

Hi Boris, what I'd like to know is the actual VLAN configuration of the switch port (link-type and tagged and untagged VLANs). When I look at the switchport coniguration here I get (among other things): ... Port link-type: trunk Tagged VLAN ID : 8, 1624 Untagged VLAN ID : 10 ... Here is my suspicion: Your ports have an access link-type with an untagged VLAN ID of 48. That would
